Technical Field

[0001] This utility model relates to the field of waterproof membrane technology, and in particular to a composite waterproof membrane with an anti-curling structure. Background Technology

[0002] Composite waterproof membranes are waterproof membranes made by combining two or more different materials through a specific process. They combine the advantages of multiple materials to compensate for the shortcomings of a single material in terms of waterproof performance, mechanical properties, and durability.

[0003] In existing technologies, waterproof membranes need to be cut and laid according to the site conditions, so gaps need to be left for splicing. In practice, adjacent waterproof membranes need to be aligned, and the traditional connection method is heat fusion.

[0004] Existing technical solutions use a heat-fusion method to connect two waterproof membranes. However, in actual use, because the waterproof membranes are spliced ​​together, the connection may not be tight; over time, the joints may warp, allowing moisture to seep in and thus failing to provide effective waterproofing. Summary of the Invention

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a technical solution:

[0026] Please see Figures 1 to 3 A composite waterproof membrane with an anti-curling structure includes a first waterproof membrane 1, a second waterproof membrane 2 disposed on one side of the first waterproof membrane 1, and a connecting mechanism 3 disposed between the first waterproof membrane 1 and the second waterproof membrane 2. The connecting mechanism 3 includes a metal sheet 301, which is embedded between the first waterproof membrane 1 and the second waterproof membrane 2. A first rubber sheet 302 is fixedly installed on the outer wall of the metal sheet 301, and a connecting shell 303 is fixedly installed on the other side of the outer wall of the first rubber sheet 302. A locking plate 304 is fixedly installed at the end of the connecting shell 303 away from the first rubber sheet 302. The outer sleeve of the locking plate 304 is... A second rubber plate 305 is provided. A groove 306 is provided on the inner wall of the second rubber plate 305 corresponding to the position of the locking plate 304. A fixed rubber pad 307 is fixedly installed on the second rubber plate 305 facing the first rubber plate 302. A movable rubber pad 308 is movably connected to the outer wall of the first rubber plate 302 facing the second rubber plate 305. An injection port 309 is provided at the top of the connecting shell 303. A flow groove 310 is provided on the outer wall of the connecting shell 303 facing the first waterproof membrane 1. The locking plate 304 and the second rubber plate 305 form a sliding structure through the groove 306. The second rubber plate 305 and the fixed rubber pad 307 are bonded together.

[0027] By adopting the above technical solution, the first rubber plate 302 is first connected to the second rubber plate 305 through the connecting shell 303 and the snap-fit ​​plate 304 via the slot 306, thereby clamping the connection end of the first waterproof membrane 1 and the second waterproof membrane 2. It also works with the fixed rubber pad 307 and the movable rubber pad 308 to elastically resist and improve the sealing performance. After the sealant is injected through the injection port 309, it flows out through the flow groove 310 to fill the gap between the first rubber plate 302 and the second rubber plate 305, thereby achieving the effect of sealing and stabilizing the connection. It can cover, press and protect the connection end of the first waterproof membrane 1 and the second waterproof membrane 2, preventing it from being exposed to the outside. Over time, it is easy for it to warp and cause leakage, affecting the waterproof effect. At the same time, it can improve the sealing and stability of the connection. A metal thin plate 301 is fixed on the externally facing position to improve the wear resistance and durability of the first rubber plate 302.

[0028] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, a clamping mechanism 4 is provided inside the connecting shell 303. The clamping mechanism 4 includes an adjusting block 401, which is rotatably connected to the outer wall of the metal sheet 301. A threaded rod 402 extends out of the adjusting block 401. A sliding groove 403 is provided on one side of the flow groove 310 on the outer wall of the connecting shell 303. A slider 404 is slidably connected inside the sliding groove 403. A movable block 405 is fixedly installed at one end of the slider 404 that passes through the connecting shell 303. The movable block 405 is threadedly connected to the threaded rod 402. A sliding structure is formed between the movable block 405 and the connecting shell 303.

[0029] By adopting the above technical solution, before injecting the sealant, the adjusting block 401 is turned with a screwdriver, causing the threaded rod 402 to push the movable block 405 to slide along the inside of the connecting shell 303. This allows the two sliders 404 to slide along the corresponding grooves 403, causing one end of the movable rubber pad 308 to slide against the corresponding first waterproof membrane 1 and second waterproof membrane 2, and to press against each other, thereby increasing the clamping force to ensure the sealing effect and preventing loosening. When the sealant is injected through the grooves 403, it is convenient to fill the gaps and prevent loosening or seepage. One end of the movable rubber pad 308 is fixed on the slider 404, and the other end is fixed on the first rubber plate 302 to prevent loosening.

[0030] Working principle: The first rubber plate 302, fixed by the metal sheet 301, drives the connecting shell 303, thereby allowing the snap-fit ​​plate 304 to pass through the slot 306 into the second rubber plate 305 for connection, thus pressing the first waterproof membrane 1 and the second waterproof membrane 2 together. The elastic contact between the fixed rubber pad 307 and the movable rubber pad 308 improves the sealing effect. The sealant is injected through the injection port 309 and flows out through the flow groove 310, filling the space between the first rubber plate 302 and the second rubber plate 305, improving the connection stability while maintaining the seal and preventing warping. Before injecting the sealant, a screwdriver is inserted into the groove of the adjusting block 401 and turned, thereby driving the threaded rod 402 to make the movable block 405 slide along the slide groove 403 via the slider 404, thus allowing one end of the movable rubber pad 308 to be fully pressed against the first waterproof membrane 1 and the second waterproof membrane 2. The slide groove 403 also allows the sealant to flow, thus achieving a sealed and stable connection.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
